The “reign upon the earth” comes after 1,000 years [Revelation 20:2,3,4,5,6,7], for the “saints” must be both resurrected and/or translated, glorified, and brought back to Heaven [John 14:1-4; 1 Thessalonians 4:17, etc] at the Second Advent and First Great Resurrection, to “reign” in Heaven, for 1,000 years [Revelation 20:4,5a,6] going over the record books of the lost [1 Corinthians 6:2,3; Psalms 149:1-9]:
[A.] The “thousand years” reign “in Heaven” [Psalms 50:5; Matthew 5:3,8,10,12, 6:20, 13:30, 24:31; Mark 10:21, 13:27; Luke 6:23, 18:22, 23:43; John 14:2-3, 17:24; Colossians 1:5; Hebrews 10:34; 1 Peter 1:4; Revelation 7:9, 14:3, 19:1; “Paradise”, Luke 23:43; 2 Corinthians 12:4; Revelation 2:7] with Christ Jesus [1 Thessalonians 4:16-17; Revelation 20:6] and
